Anyone who wishes to discharge dredged or fill material into the waters of the U.S., regardless of whether on private or public property, must obtain a Section 404 permit from the U.S. Army Corps of Engineers (Corps) and a Section 401 Water Quality Certification (WQC) from the state.
Anyone who wishes to discharge dredged or fill material into isolated wetlands in Ohio must obtain an Isolated Wetland Permit from Ohio EPA.
The 401 Water Quality Certification and Isolated Wetland Permitting Section reviews applications for projects that propose the placement of fill or dredged material into waters of the State, including streams, lakes and wetlands. The section also reviews required mitigation of issued permits and performs wetland research.
To make a complaint and/or report illegal fill activities, please email the Complaint Form [Word] to EPA401Webmail@epa.ohio.gov.
New 401 Rules Will be Effective Jan. 2, 2017
New 401 rules (OAC 3745-32-01:03) will be effective January 2, 2017. Click here for information on the new rules.
With the new 401 rules, changes will be required to the 401 WQC application form, impact tables and application instructions. Applicants will no longer be required to submit a preferred, minimal degradation and non-degradation alternative for their project. An alternatives analysis will still be required, but must be conducted in accordance with 40 C.F.R. Part 230, OAC 3745-1-05 and OAC 3745-1-54. Information on how to complete the alternatives analysis will be provided in the application instructions and forthcoming guidance.
Prior to the effective date, the new forms, impacts tables and instructions will be posted on our website. Ohio EPA will continue to accept the old application form for six months after the effective date (July 2017) after which the new application will be required.
Stay tuned for more details regarding the changes.
